In order to obtain huge profits and disregard the interests of consumers, counterfeit and inferior wire power supply manufacturers mass produce inferior wire power products, disrupt the wire power market, and harm the interests of customers.

So, it is very important to choose the products of the power cord and power cord manufacturers correctly. What kind of products are in compliance with national standards? In order to improve product quality and ensure that products comply with national standards, wire power supply companies that meet national standards require strict control in the purchase of raw materials, production equipment, and production processes.

1. It is advisable to repeatedly bend a wire end by hand. Anything that is soft to the touch, good in fatigue resistance, flexible in plastic or rubber, and free of cracks on the wire insulation is a premium product.

Second, the appearance of wire power products produced by good wire power brands meets standard requirements: smooth and round, uniform color. The appearance of fake and inferior products is rough and dull. For rubber-insulated soft power supplies, the appearance must be round, and the sheath, insulation, and conductor are tight and not easy to peel off. The fake and inferior products have a rough appearance, large ovality, and low sheath insulation strength, which can be torn off by hand.

Third, the conductor is shiny, and the DC resistance and the structure size of the conductor meet the requirements of national standards. The products of electric wire ul power line manufacturers that meet the requirements of national standards, whether they are aluminum conductors or copper conductors, are relatively bright and free of oil. Therefore, the DC resistance of the conductors fully meets national standards, has good electrical conductivity and high safety.

Fourth, the length is accurate. Length is the main intuitive way to distinguish between conforming to national standards and counterfeit and inferior products. The length of the wire power supply products that meet the requirements of national standards meets the national standard 100 ± 0.5m (that is, 100 meters as the standard, with an allowable error of 0.5 meters), protecting the interests of consumers.

Electricity safety has always been a topic that people have always attached importance to, so the purchase of wire power can not be ignored. The above are the knowledge points shared by UL power cord manufacturers on how to distinguish between genuine and fake power cords, hoping to help everyone.
